Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0603Y0500331MXT is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 pF
• Tolerance: ±20%
• Voltage rating: 50V minimum
• Temperature coefficient: X7R
• Package designation: 0603 (1608 Metric)
• Mounting technology: Surface Mount, MLCC
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The substitute part KGM15AR71H331MT from KYOCERA AVX meets all specified electrical and mechanical requirements. Physical dimensions remain within acceptable tolerance for 0603 package specifications, with minor variations in thickness (0.90mm vs. 0.80mm) that do not affect PCB assembly or circuit performance.

Parameter Comparison

Engineering Selection Recommendations

Both the primary part (0603Y0500331MXT) and substitute part (KGM15AR71H331MT) maintain Active product status with identical regulatory compliance certifications. Selection between these components should be based on:

• Availability and lead time requirements
• Cost considerations
• Existing supply chain relationships
• PCB layout constraints, particularly regarding the 0.10mm thickness differential

The thickness variation of 0.10mm (0.80mm to 0.90mm) remains within standard 0603 package tolerances and does not impact standard PCB assembly processes or component placement accuracy.

Frequently Asked Questions (FAQ)

Q: Can KGM15AR71H331MT be used as a direct replacement for 0603Y0500331MXT?

A: Yes. Both components share identical electrical specifications (330 pF, ±20%, 50V, X7R) and package designation (0603). Physical dimensions are within acceptable tolerance for the 0603 form factor.

Q: What is the significance of the X7R temperature coefficient?

A: X7R designates a ceramic capacitor with ±15% capacitance change across the -55°C to 125°C operating temperature range. This specification ensures stable performance across the full operating temperature window for both parts.

Q: Are there differences in application suitability between these parts?

A: The primary part (0603Y0500331MXT) is specified for high-reliability and boardflex-sensitive applications with soft termination features. The substitute part (KGM15AR71H331MT) is designated for general-purpose applications. Both meet the same electrical and compliance requirements; application selection depends on specific reliability or mechanical stress requirements.

Q: Does the 0.10mm thickness difference affect PCB assembly?

A: No. Standard PCB assembly equipment accommodates component thickness variations within 0603 package specifications. Both parts are compatible with standard pick-and-place and reflow processes.

Q: What certifications apply to both parts?

A: Both components are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling requirements.
